Answer:

Ariel answer is wrong.

Step-by-step explanation:

Given that Ariel had done a Math problem for a triangle with sides

9,15 and 12.  She concluded that these sides are not that of a right triangle.

To check whether Ariel is right:

Greater side = 15

Hence greatest angle will be opposite 15

Let us check pythagorean theorem

smaller sides are 9 and 12

Square and add them

9 square +12 square = 81+144 = 225 =15 square

We find that Pythagorus theorem is satisfied

Hence it is concluded that the triangle is right angled and Ariel was wrong

2 · 2 = 9/2

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(18, 4) = 2. In the next intermediate step cancelling by a common factor of 2 gives 9

PolarNik [594]
M+B=640

M=3B

----------------------------------------------

Therefore:

3B+B=640

4B=640

B=640/4=160

----------------------------------------------

M+160=640

M=640-160=480

Therefore, Mike had sold 480 cars.

Last year a pair of shoes cost $35. This year the price of the shoes has increased to 115% of the original price. What is the ne
maria [59]
When a problem says that the price was increased by 100% + n%, it means you add on n% percent of the original price. In this problem, the original price was $35. The new price is 115% percent of the original price. So all we need to do is find 15% of the original price and add it onto the original price to find the new price.
$35 * 0.15 = $5.25
$35 + $5.25 = $40.25
The new price of the shoes is $40.25.
